Summary

A homeowner in Llewellyn Park scheduled their annual liquid-cooled generator maintenance. The goal was to keep their generator ready for outages and spot any potential problems before they could cause a real interruption.

The Work

Completed full generator inspection, including oil and air filter changes, spark plug replacement, and coolant check
Inspected battery and checked gas fittings for safe operation
Noticed a high voltage error code on arrival and attempted resets
Diagnosed automatic voltage regulator issue and replaced the part

The Outcome

Routine maintenance kept the generator in peak shape, but our visit also caught an electrical issue before it could cause a failure during an emergency. This proactive approach helps prevent unexpected downtime and keeps standby power reliable.
